If I'm going to be honest here then what killed the site for me is the verification process implemented here. It's too much of a hassle to be honest and the average user doesn't want to deal with that. Also, at the very beginning, I invited a bunch of people to this site. I've gotten several messages later on from people that weren't able to make accounts because no one verified them. So I'm sorry to say this but of course the site will die like that.
